Can't install - communication error

[KevinDFZ]

I get the "communication error" when I try to install AutoCAD 2015 using the installer. So I tried to find the "download now" option, but there isn't one? Neither is a "browser download" option. The only option available in the software download page is "install now". So how do I install this...?
